Embodiment 1

[0064] 1. Composting treatment of green waste

[0065] 1) Pulverize the garden plant branches and trunks to make a pulverized product with a particle size less than 10mm, spray water in the pulverized product, make the water content of the pulverized product 60%, add urea to adjust the carbon-nitrogen ratio of the pulverized product to be 35: 1;

[0066] 2) Add agricultural microbial inoculum to the pulverized material and mix evenly, wherein, the number of effective viable bacteria in the agricultural microbial inoculum is ≥200 million / g, the pH value is 5.5, and the effective viable bacteria include actinomycetes, thermophilic bacteria, White rot bacteria, nitrogen-fixing bacteria, phosphate solubilizing bacteria, potassium solubilizing bacteria, cellulose decomposing bacteria, etc., the addition amount of the agricultural microbial agent is to add 2kg of the agricultural microbial bacteria per 1000kg (dry weight) of garden waste pulverization agent;

[0067] The agricultu...

Embodiment 2

[0089] The composting treatment step of greening waste, in addition to regulating the water content of the crushed waste to be 55%, adjusting the carbon-nitrogen ratio of the material is 40: 1, and the addition of the agricultural microbial bacterial agent is that the garden waste is pulverized per 1000kg (dry weight). Add 1kg of agricultural microbial bacterial agent in the thing, except that the moisture content of the heap body is controlled to be 55% in the fermentation process, all the other are the same as in Example 1. The performance index test results of the prepared landscaping waste compost are shown in Table 1.

[0090] The preparation steps of the cultivation substrate are the same as in Example 1 except that the volume ratio of greening waste compost, vinegar grains and peat is 4:2:4. The test results of the performance indexes of the prepared plant cultivation substrate are shown in Table 2.

Embodiment 3

[0092] For the composting treatment steps of greening waste, in addition to adjusting the water content of the crushed waste to 65%, adjusting the carbon-nitrogen ratio of the material to 37:1, the organic material decomposing agent is used for composting and fermentation treatment, and the amount of organic material decomposing agent added is Add 8kg of organic material decomposing agent in the garden waste pulverization of every 1000kg (dry weight), except that the moisture content of the heap is controlled to be 65% in the fermentation process, all the other are the same as in Example 1. The performance index test results of the prepared landscaping waste compost are shown in Table 1.

[0093] The preparation steps of the cultivation substrate are the same as in Example 1 except that the volume ratio of greening waste compost, vinegar grains and peat is 5:3:2. The test results of the performance indexes of the prepared plant cultivation substrate are shown in Table 2.

Abstract

The invention discloses a plant cultivation medium and its preparation method. The cultivation medium includes a garden greening waste compost, vinegar residues and turf, and is prepared through blending the garden greening waste compost, vinegar residues and turf according to a volume ratio of 3-6:2-3:2-6. The cultivation medium improves the physical and chemical properties of original mediums, reduces the application amount of a nonrenewable medium turf which is massively used in the production of flowers at present, allows the vinegar residues and garden greening wastes to be massively used to realize changing of wastes into valuables and resource recycle, and has obvious social, ecologic and economic benefits.

Description

technical field [0001] The invention relates to a nutrient matrix for cultivating plants and flowers and a preparation method thereof, in particular to a nutrient matrix for soilless cultivation of plants, herbs and flowers and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of the cultural level, people's requirements for the living environment are getting higher and higher, and the application of grass flowers is also increasing. At present, the main raw material of the cultivation substrate required in the production of agriculture, forestry and flower industry is peat substrate, which can be widely used in flower cultivation, rice seedling cultivation, indoor garden plant cultivation, vegetable seedling cultivation, cotton seedling cultivation, lawn cultivation (golf course construction) ), soil improvement and organic fertilizer manufacturing, etc. [0003] Peat, also known as peat, peat soil, black so...
